Preparing for New JavaScript Features
- Learn about upcoming JavaScript features to prepare for them and potentially influence their development.
- Get involved in discussions about these features to shape the future of JavaScript.
Promise.try Simplifies Asynchronous Code
Promise.try
simplifies handling functions that may or may not be promises.- It allows using
.catch
for non-promises, streamlining error handling.
Math.sumPrecise Ensures Accuracy
- JavaScript's
Math.sumPrecise
offers precise number addition, unlike regular operators. - It's more computationally expensive than regular addition but guarantees accuracy.
